I was having a tire test mounted on my wheel for another car (sizing issues, looking for a good setup) and while at the shop I noticed a little display for these dynamic wheel weights. Seems they're a very flexible stick on cylinder with.....as best as I can explain it.....steel shot in varying weights inside, free to move. Seems like an interesting concept. Just wondering if anyone has any experience? This just piqued my curiosity.

That is all which is used by Toyota anymore and from what I hear they work much better then the lead weights. And you know lead being lead and the EPA...yada, yada
I'll be using them on our Celica within a couple of weeks once I get a new wheel and new tires. If they work out there, the Vette will get the treatment as I've got one wheel that's still out of whack.
They had these back in the 70's only they looked like a donut with a plate on it that would sandwich between the wheel and drum/rotor. They worked really well. The only downside to them was that you'd hear them every time you take off. Shew Shew Shew Shew. (how's that for a sound description?)
The weight can move, but it is not obvious as to what force actually makes the weight move to the location that will balance the whole assembly.
Centrifugal force exerts an outward force on the weights, but what force makes the weight move circumferentially to offset an out of balance? It seems like the weight would just spread out evenly along the circumference.
What if the range of variable weight is on the heavy side of the wheel instead of the side it needs to be on to balance? Do you have to do a rough balance to locate the weight band?

I had the same questions. The link did nothing to explain how it works. Unless it goes all the way around the wheel, you'd have to have a rough balance first, or put it where you took the old weights OFF. Even then, it seems like the weight would migrate to the already heaviest part of the wheel.
From the installation information on their website, you do need to do a "rough balance" first ...
My question is ... so I have all these little ***** in the system, and I accelerate the wheel ... wouldn't all the little weights migrate to the "end" of this system, throwing everything out of balance ..... and on the opposite side .... under heavy braking ... the ***** would move to the other end of this system ....
Sounds like total to me ..... I wouldn't install it .....
